' CEREAL COFFEE OR, COFFEE SUBSTITUTE.

Specification of Letters Patent.

Patented Aug. 5,1913.

No Drawing. Original application filed May 20, 1912, Serial No. $98,585.Divided aiidthis application I filed June 23, 1913.

Serial No. 775,232.

To all whom it may concern i die it known that I, JOHN H. KELLOGG, acitizen of the United States, and a resident of the city of BattleCreek, in the county of Calhoun and State of Michigan, have inventedcertain new and useful Improvements in Cereal Coffee or CoffeeSubstitute, of which the following is a specification.

This invention relates to improvements in cereal coffee or coffeesubstitutes and constitutes a division of my prior application,

Serial No. 698,585, filed May 20, 1912.

One of "the primary objects of the invention is the provision of acereal coffee whichmay be readily and cheaply manufactured and which maybe prepared for immediate use merely by adding hot water to thepreparation.

Another object is to-utilize the residue from which the soluble extracthas been removed as a carrier to receive upon the surfaces of itscomposite granules the concen trated extract previously removed.

Other objects and advantages of the invention will be readilyappreciated as the invention is better understood from the folv lowingdescription and the appended claims:

In carrying out my invention I prefer to employ a cereal coffee producedby combinin malted cereals such for instance as malted wheat, barley, orrye, and barley sprouts, with bran and unmalted wheat, rye and barley,and roasting the whole together. It should be understood, however, thatthe above mentioned constituents are merely illustrative and that theterm cereal coffee hereinafter employed may comprehend any of the socalled-cereal coifees now on the market or other preferred materials, orcompositions of similar character.

The cereal coffee employed is first thoroughly roasted or baked and thenboiled to extract the soluble matter, the boiling being carried on for apreferably froni one-half hour to one hour acctirding to variations inconditions. It is however, desirable to boil the mixture untilsubstantially all of the soluble matter has been extracted therefrom.The extract or liquor is then drained or otherwise sepa. rated from theinsoluble grains or soli residue, which is usually in the form of agranular mass, and is then concentrated or evaporated to a syrup-likeconsistency.

limited period of time,

-cofi'ce which consists in extracting the solu 'lhe insoluble grains orgrounds from which the extract has been removed arefirst] dried and thenapproximately one-half of this insoluble residue is mixed with the com;centrated extract or syrup, so that the exa teriors of the insolublegranules are thorr oughly coated with the extract, the mass be. ing thenthoroughly of extract. If desired, the material'may be. coarsely groundto separate particles which may haveadheredtogether during the dry- Itwill be manifest that the extract is? thoroughly mixed with theinsoluble granular residue so that the surfaces of the grounds orgranules are coated with the exaccessible, so that it will be dissolvedat once from the anules when brought into contact with boiling water.Sugar in any desired quantities may be added to the ex,- tractbefore thesame is applied to. the granules so that the beverage resulting from theaddition ofboiling-water will possess the desired degree of sweetness.

It will be obviousthat since the condensed or evaporated extract iscarried on the surface of the insoluble grounds or granules it maybevery read'ly and quickly dissolved by curing hot Water over the groundswith the result that a pleasing beverage may be prepared very quicklyand easily. 1lethe product is capable of use without drymg I prefer,nevertheless, to thoroughly dry the coated grounds for the reason thatwhen thoroughly dried the roduct may be kept for long-period wit outspoiling.

I claim:

1; The process of manufacturing cereal coffee consisting of extractingthe liquor from cereal cofi'ee, evaporating the extract, and mixingcereal coffee grounds withthe extract to coat the surfaces of saidgrounds. 1

2. The process of tract-ing t-he 'li'quor and evaporating it to asyrup-like consistency andmixing cereal coffee groundswith tho -extractto coat the surfaces'o'f the grounds with the extract.

9. A coffee substitute consisting of a granular mass of the insolubleresidue from a cereal cofiee coated With a concentrated soluble extractof the coffee dried thereon.

10. A coffee substitute consisting of cereal coffee grounds or residuein granular form, the granules having a surface coating of cereal coffeeliquor evaporated to a syruplike consistency and dried thereon.

11. A coffee substitute consisting of cereal coffee grounds or residuein granular form, the granules having a surface coating of cereal coffeeliquor evaporated to a syruplike consistency. 7
